comment Make disk/disk copy slower
If you are seeking to limit disk-to-disk copy speed in an effort to be "nice" to other I/O-bound processes in the system, you are probably better off taking advantage of the kernel's ability to tune I/O scheduling instead. Specifically, ionice can be used to ensure that your disk-to-disk copy process is scheduled I/O at a lower priority than regular processes.

comment `ps | grep | kill` aborts my script prematurely
If possible, I'd recommend using pkill instead of the ps|grep|... pipeline you're using now. pkill is immune to the problem you noted, whereby grep on the process list finds the grep process itself. (There are tricks to avoid that, but pkill is cleaner, IMO.)

comment What is a solid iptables configuration for my desktop?
REJECT is not a valid policy target (ACCEPT, DROP, QUEUE, and RETURN are the only ones allowed there).

These days, you'll want the new curses, or ncurses.

comment How to configure an OpenWrt 10.03 router to forward an IPv6 connection to the clients?
@gaskopeter: Scroll to the bottom of the HowTo guide I linked to. You should find a minimal set of ip6tables rules there that implement a stateful firewall.

comment From df device name to physical drive name (vendor / type)
@Horst: Try hdparm -I /dev/sdb instead. /dev/sdb3 is most likely not a drive, but a partition, and hdparm needs a drive.

comment /etc/crontab permissions
I disagree somewhat. It is not merely "security by obscurity" to want to keep cronjob details away from regular users. I would call it a (small) part of "defense in depth". Basically, you're right, someone could POSSIBLY determine the contents of my crontab by watching all processes over a length of time, but IMO, that's just fine. Any extra amount of time that a non-root intruder is forced to spend to analyze weaknesses in my system is extra time that I GAIN to detect his presence and take remedial action.
